Title: detecting an unreiable cable.
Post by: ferg22 on June 05, 2018, 10:13:09 pm
HI,

Perhaps this is already supported, but we have a suspect cable. If we wiggle the cable were goes into the network adapter it fails. Not sure if it is the cable's RJ45 or the adapter, I need to test.

Does the pocketethernet support any type of continious monitoring which allows it to report the cable's state while I wiggle the cable ends?

Regards All

Plug on end into the pockethernet and the other into the loopback end of the adapter.

In the pockethernet app run the BER test.  Set it to 1000, 1518 bytes, 10M.  This will run a test that runs for nearly 2 and a half minutes.  It also shows errors in the cable, so if you monitor how many errors are detected you should be able to detect a spike in errors when you poke the right part of the cable with a stick :)

By default not really, you could indeed try the BER, and follow the error count. You could also try the TDR graph if it shows any bump, try it while the cable is connected to another turned off Ethernet device and try it with the cable left open.

Thanks - just the job.
